直径3200变换炉的设计 【摘要】本次毕业设计主要是化工容器—直径3200 mm变换炉的设计，主要介绍了变换炉的发展背景和在化学工业中的应用。本设计是变换炉在工作压力为0.8Mpa，操作温度为470℃时，参考了GB150, JB/T4710-92《钢制塔设备标准》,JB4709-2007《钢制压力容器焊接规程》等标准。对壳体、封头及附件壁厚的设计计算，并考虑了基本风压（0.35Mpa）和地震烈度（7级）时的强度、稳定性校核，包括筒体应力、塔设备压力实验时的应力、裙座轴向应力的校核，并对紧固件地脚螺栓进行了设计和校核。然后对于有接管或人孔的开口处进行了补强设计，对标准件法兰进行了选用。 【关键词】第一变换炉、设计、校核方法 Abstract: The graduation designing is the mainly about the chemical containers-Transform furnace which the diameter is 3200 mm.It mainly introduced the background of the development of pressure vessels and the application in chemical industry.This design is about the caculating of the Transform furnace’s shell,head,annex wall’s thickness when the working pressure is 0.8Mpa and the operating temperature is 470℃,and I also made reference to the designing standards GB150, JB/T4710-92“steel tower equipment standards ”and JB4709-2007 “protocols steel pressure vessel welding” and so on,the checking of the strength and the stability when considering the basic wind pressure is 0.35Mpa and the seismic intensity of the earthquake is 7,including the cylinder stress,the stress of the tower equipment at the time of pressur expirenemt and the axial stress .we also designed and checked the nachor bolts which is used for fasteners. Then we designed the reinforcement for the opening holes .The flange is select through the standard.
